OS2 Structural Safety



Intent 1:

To limit the probability of structural failure at the point of attachment of stairs, which could lead to an inability to support vertical building loads or lateral earth loads, which could lead to:

  • structural failure of the stairs, or
  • where the foundation wall encloses interior spaces, compromised integrity of elements supported or protected by foundations, which could lead to the ingress of moisture from the ground, which could lead to deterioration.

This is to limit the probability of harm to persons.
